Calcofluor White: Tips for Improving Its Use Brian J. When we suspect acanthamoeba infection, we use Calcofluor white M2R, an inexpensive (about 10 cents per test), colorless compound that is widely available commercially (from American Cyanamid. meliloti 1021 was grown with 500 μg/ml streptomycin, and S. For CLSM analysis, bacterial and yeast biofilms were stained with LIVE/DEAD BacLight, FUN1, and calcofluor white, and images were obtained over the depth of the biofilm. The cell suspension was diluted serially and inoculated onto YPD plates, each containing one of the following: 10 μg/ml benomyl (Sigma-Aldrich), 100 mM HU (Sigma-Aldrich), or 50 μg/ml calcofluor white (Sigma-Aldrich). ulcerans, and M. BY2 growth media (see Recipes) 12.

Thereafter, the cover slips with untreated and treated biofilms were stained with 300 mg/ml calcofluor white (Sigma) [calcofluor white binds to the sugar residues in the biofilm polysaccharide and stains them blue] and 0. Calcofluor white may be obtained as fluorescent brightener 28 (Tinopal UNPA-GX) in the salt or the free acid form (Sigma Chemical Co. Staining of fibre sections revealed two distinctive features of the CFML and cell wall interfaces in the fibre tissue: enlarged intercellular regions and smaller, strongly staining, CFML bulges. During encystment, the cell surface acquires a Calcofluor-specific material.

In order to measure cell size at division and percentage of multi-septated cells, strains were grown in low nitrogen containing DMM medium to an ∼5x106 cells/ml and stained with calcofluor white (Sigma), which specifically stains cell wall and septum ,. 1% the stain was added onto the section and a coverslip placed on it. 01% solution in water and add a few drops of 1N NaOH. Effect of sodium orthovanadate on glycosylation of the phosphopeptidomannans involved in the cell–cell aggregation of the yeast Kluyveromyces bulgaricus. To detect chitin, 30 μl of washed cells was mixed with either no fluorophore or with calcofluor white (BactiDrop, Remel, Lenexa, KS), 2 μg/ml of wheat germ agglutinin-FITC (Sigma), or 2 μg/ml of synthetic chitin-binding domain-rhodamine. The remaining dye was then rinsed from the block face by immersing it in distilled water for 2 min.
